As a homeowner, I primarily write about weather safety tips that everyone should know in order to protect their home and family during major weather events. I especially like to share seasonal "outside the box" ideas that most wouldn't think of in the Spring, Summer, Winter, and Fall. The weather events I've personally experienced include: Hurricanes (while living in Florida), Tornadoes (while living in Indiana, Texas, and Tennessee), Earthquakes (while visiting California), Blizzards (while living in New York and Indiana), and Flooding (while living in Tennessee).
